Currently the focus of many startups is on sharing life experiences. Foursquare, Instagram, Vine are all great examples of this. Do you think that this kind of ideas are among the organic ones PG describes in one of his essays [1]? Did the founders that started Instagram feel the need to share their photos with all the world? Many startups are following this trend, so something must be going on, but my guts tell me that it will pass because it's not tapping in our real needs, but just exploiting the rise of the mobile phone as a medium.[1](http://www.paulgraham.com/organic.html)
